I have a Pear tree that I have had for about nine years know, It only grows pears on one branch of the tree. The same branch every year. But it also has little pears about the size of berries all over the rest of the tree. The tree is over ten feet tall and has very good growth. I have pruned the tree this year and are awaiting spring to see if I get more than ten pears.If anyone knows what is going on with my tree.Can you please help.
